So you may react to asynchronous events, there is the possibility to activate a process
interrupt. A process interrupt interrupts the linear program sequence and jumps
depending on the master system to a corresponding Interrupt routine. Here you can react
to the process interrupt accordingly.
With CANopen the process interrupt data a transferred via an emergency telegram.
Operating with CPU, PROFIBUS and PROFINET the process interrupt data were trans-
ferred via diagnostics telegram.

16bit µs value at the moment of the interrupt
µs ticker
In the SLIO module there is a 32 bit timer (µs ticker). With PowerON the timer starts
counting with 0. After 2
32
-1µs the timer starts with 0 again. PRIT_US represents the lower
2 byte of the µs ticker value (0 ... 2
16
-1).
Via the parameterization you may activate a diagnostic interrupt for the module. With a
diagnostics interrupt the module serves for diagnostics data for diagnostic interrupt
incoming
.
As soon as the reason for releasing a diagnostic interrupt is no longer present, the diag-
nostic interrupt
going
automatically takes place. All events of a channel between diagnostic
interrupt
incoming
and diagnostic interrupt
going
are not stored and get lost. Within this time
window (1. diagnostic interrupt
incoming
until last diagnostic interrupt
going
) the MF-LED of the
module is on.
